A [4](hetero)helicenium cation was resolved using the hexacoordinated phosphorus‐containing binphat anion (see picture: N, blue; O, red; C, gray). Its absolute configuration was determined by vibrational circular dichroism spectroscopy. The barrier of interconversion of its enantiomers is higher than that of [6]helicene.
